Description Stephen Herr 2014-05-15 18:46:26 UTC 
Description of problem:
Any of the System Details pages are very slow for no good reason if the system happens to have many virtual guests (in my case, 2000, or at least 1 guest that has registered 2000 times). This is because to determine what icon to display next to the server name we have to see if the system is a virtual host, we are currently doing that by having Hibernate hydrate every guest and then returning "True" if the list of guests is larger than 0.

This is stupid, instead we should just have a query that returns a "1" or something if the server is a virtual host.

How reproducible:
Always

Steps to Reproduce:
1. Register a host's guest several thousand times
2. navigate to Systems -> <system_name> -> <any of these pages>

Actual results:
Those pages are all very slow

Expected results:
They should be an appropriate speed and only load details for the guests if they actually need that information.
